# This script is used to coerce certain commands which rely on the presence of
# a go.mod into working with our repository. It works by creating a fake
# go.mod, running a specified command (passed via arguments), and removing it
# when the command is finished. This script should be dropped when this
# repository is a proper Go module with a permanent go.mod.
